Or you could do both. My camera is set to save two images per shot--one RAW and one JPEG. This is a great learning tool for a beginner like myself. The default settings yield somewhat over-saturated colors for JPEGs, so it's always nice to have a side-by-side comparison for every picture.
Shooting raw lets me save a few percent of photos where exposure is a little wrong. This is huge on its own, and you mention it.
It also lets me stretch things and make scenes work which would otherwise exceed the dynamic range of the exposure and the built in tone mapping would guess wrong.
Storage is cheap these days. If you're not doing something boost-shooting/burst intensive, why not shoot raw? Most of the time the result will be the same, and occasionally it will let you do much more.
And, here, IMO, the rant is particularly off base. A big part of ProRAW is being able to have big linear HDR stacks, which is immensely powerful and absolutely will let you do things you couldn't do any other way.
